Abstract

Background: Worldwide, stroke accounts for 15 million cases annually. Despite improved understanding of its pathophysiology, an effective treatment is yet to be available. Objective: This review aims to expound ischemic stroke pathophysiology from a bio-molecular perspective, and present two peptides, namely Tat-NR2B9c and Tat-NR2Bct-CTM, which has been proven to attenuate neuronal tissue damage in ischemic stroke. Methods: Scoping review of several electronic databases: PubMed, Medline, Researchgate, NCBI, SpringerLink, and Google scholar. Search query included: ischemic stroke, NR2B, DAPK1, nNOS, NOX, Tat-NR2Bct-CTM and Tat-NR2B9c. Results:  It is recognizable in a sense, that the pathophysiology pivots on the NR2B-DAPK1 and PSD-95-NR2B interactions. Tat-NR2Bct-CTM and Tat-NR2B9c thwarts NR2B-DAPK1 and PSD-95-NR2B interactions, respectively. These peptides show significant reliability, with the former capable of reducing free DAPK1 by 92,85%, and the latter, the first stroke treatment in two decades to reach Phase 3 clinical trials. Conclusion: These results strongly support Tat-NR2Bct-CTM and Tat-NR2B9c as effective means to reduce neuronal tissue damage in ischemic stroke.

Abstract

Background: Amyotrophic Lateral Sclerosis (ALS) is a fatal neuromuscular disease with a survival period of less than 5 years. Although the past decade has shown a major growth of interest in Edaravone research due to its superior efficacy, a growing number of research done on Riluzole combinations for ALS therapy. Objective: A systematic review is needed to compare the patient outcomes as shown in the ALS functional rating scale (ALSFRS-R) of Edaravone and Riluzole combinations. Methods: This research is a systematic review from PubMed, ProQuest, and Science Direct. The studies included were randomized controlled trials (RCT) and post-hoc analysis of RCT published from 2012 to 2023. This research included 16 studies (11 RCT studies and 5 post-hoc studies of RCT). The studies discussed the patient population, side effects, and ALSFRS-R scores. Results: Edaravone showed better efficacy than Riluzole combination in maintaining ALSFRS-R score with mean difference between Edaravone (MD=2.19, 95% CI: 0.42-3.96, p=0.02) and Riluzole (MD=1.67, 95% CI: -0.19-3.52, p=0.08). The meta-analysis showed heterogeneity in both Edaravone (I2=90%, p<0.00001) and Riluzole (I2=77%, p=0.004) studies. Conclusion: The results conclusively showed that Edaravone was more efficacious than the explored Riluzole combinations so far. Nevertheless, Riluzole-Masitinib showed promising results to be further explored.
